Function of the trechea?
The trachea is also known as the windpipe. It is a bony tube, which connects the nose and mouth to the lungs, hence is an important part of the respiratory system in vertebrates. It is a rigid muscular tube located in front of the esophagus, which is approximately 4.5 inches long and 1 inch wide. Its inner diameter is about 21 to 27 millimeters and the length is approximately 10 to 16 centimeters. There are approximately 15 to 20 incomplete C-shaped cartilage rings, which protect the trachea and maintain the airway. The muscles of the trachea are connected to the incomplete rings and contract while coughing, which reduces the size of the lumen of the trachea to increase the flow of air. The cartilages ensure that the larynx and the trachea do not collapse, when there is no air in them.
